CHECKING THE OIL LEVEL.

The jacks are normally supplied filled and ready for use. However before

using the jack for the first time, the oil level should be checked. The oil used

should be a high quality hydraulic oil of HVI ISO32 viscosity, e.g. Hi-force

HFO32.

Remove the dipstick (See figure 1) and check the oil level. The maximum

level is marked on the dipstick. The level should be within 5mm of this mark.

The dipstick should be screwed fully into position to determine this level.

OPERATION OF JACK. See Figure 1.

Note: The permissible working load and stroke of the Jack are marked on the

side.

The Jack (1) has an in-built hydraulic pump which is worked by means of an

operating lever (2), under the control of the operator. The piston (3) is raised

on each downwards stroke of the lever. For lifting, the lever is placed fully into

the operating quadrant (4). Three positions are provided to enable the user to

choose the best ergonomic position. For lowering, the piston the lever is

removed from the quadrant and placed into the release screw (5). Turning this

anticlockwise will allow the piston to descend. The amount this is rotated will

control the speed of decent. Only open a very small amount (approx. 5°) at

first. Rotate clockwise, hand tight after use, to ready the jack for the next

operation.
